As usual some of my planned activities fell by the wayside due to running into other Atari related issues.

However, the install of the new 40Mhz booster was not one of them!!

Here you can see the board installed and running, tied down to 8Mhz for the first run:

Once running, I removed the link to ground that tied it to 8Mhz, then what was I to do, but benchmark it, so here is a direct comparison using GEMBench, of my 32Mhz MK1 booster vs my MK1.5 at 40Mhz.

Here's 32Mhz first:

And here's 40Mhz:

As you can see, there is quite a noticeable difference, so I have to say well done to exxos for doing such a good job

The only problem I ran into was gettinin it into the slot, as I bent a single pin on the fist attempt. It was a bit odd because all of the other pins went in no problem, apart from one at the top end of the left hand row.

Luckily it was a minor task to remove the booster and straighten the pin, and everything went in smooothly on the 2nd attempt.

Oviously more testing is required, like the almost obligatory Elite 2 test, and a GB6 burn in test, but I'm confident it will run well.

The final piece of the puzzle will be to fit a switch so I can flip between 8Mhz and 40Mhz.
